SILVIO A. SCHEWCZIK, 0F VIENNA, AUSTRIA-HUNGARY.

Be it known that I, SILVIO A. Scrmwozm, a subject of the Austro-Hungarian Emperor, residing at Vienna, Austria-Hungary, have invented certain new and useful Improvements in Spring-Tires for Wheels, of which the following is a specification.

The present invention relates to spring tires for vehicle wheels and has for its purpose to provide a tire which will serve all the advantages of the pneumatic tire and yet be freefrom the many disadvantages attending the use of the same.

Generally stated, the invention embodies a resilient or cushioning means interposed be tween the wheel felly and an outer rim or tread, thus removing such means from the wear to which the cushioning means is usually subjected, and-the tread is of such structure as to retain the cushioning means in its proper'position, and thus provide a smooth and even running surface for the wheel.

With these objects in view, my invention is shown in its preferred embodiment in the accompanying drawings, wherein- Figure 1 is a longitudinal section of the invention, Fig. 2 is a transverse section of Fig. 1, Fig. 3 is .a similar view showing a slight modification, Figs. 4 and 5 are respectively a longitudinal section and top plan view of a modified form of tread member, and, Figs. 6 and 7 are corresponding views of a further modification.

Referring to the diiferent views in further detail and wherein like letters of reference indicate corresponding parts in the different views shown, a design-ates a wheel felly or rim which is of substantially U- sha e in cross section (see Figs. 2 and 3) an fitting wlthin said mm and co-e'xtensive therewith 1s asecond rim or cushion retaining means 0 which comprises a single sheet Y the links.

port a tread member which in series consti tute the outer rim of the wheel. The several tread members comprise each a link 9 constructed of metal and are of such design on their under sides 7 as to provide a complementary bearing surface or seat for the balls d. Each of sa1d links is further provided with attaching means at its ends as shown whereby to interengage in a manner that will permit of relativev movement between the several tread members to compensate for inequalities in the road over which the vehicle may be traveling. The structure of the links is such as to receive a wearing block 9 of any preferred material, such as leather, rubber, wood or the like. The substance of the block is arranged in a series of separate strips or sections dis osed either transversely or longitudinal y of the tread block, (see Figs. 5 and 7). p

In lieu of the felly a; as employed in Fig. l the design of felly a shown in Fig. 3 may be used. In this instance the several other elements of the tire are correspondingly modified. Thus the retainer rim 0' is of a Y design that will permit its reception within said felly a. The cushioning ,means co1n prises a plurality of rubber cylinders (Z' arv ranged in substantially the manner shown in Fig. 1, and each pair of WlllCh supports a tread retaining link 9 The wearing surface g( for each of the links 9 may hkewise be of the same material employed in the type of tread shown in the figures above described; I I

In the structure shown in- Figs. 4; and 5, the tread links 9 have the wearing surface thereof in the form of blocksg dlsposed transversely of the links. And in that structure shown in Figs. 6 and 7, the links g have the blocks 9 disposed lengthwise of Having thus described the invention, what is claimed as new, 1s:- Y Y 1. In a wheel-tire, the combination with.

"spherical depressions therein, means engagin intermediate said depressed portions for ad ustabl supporting said ring upon the wheel fel y, cushioning members of spherical desi sea-ted within the depressions of the cushlon retaining means, and a tread comprising a plurality of connected members each of which members has its under side designed with semi-spherical depressions adapted to receive said cushioning means.

3. In a wheel-tire the combination with the felly, of a cushion retaining means adjustably' supported thereon and provided with a plurality of depressions, said adjusting means comprising pins carried by the wheel felly and seated within the grooves formed by the. depressed portions, cushioning members seated within said depressed portions, a wheel tread comprising a plurahty of connected members having their under faces provided with depressions adapted to receive said cushioning members, and a tread substance carried by the individual members constitutin the wheel tread.
